So it's a bit far off as I'm not getting married until October of 2016, but I am trying to get a guest list figured out in order to better know what my budget should be. We originally planned on having our wedding on a Monday in order to have it on Halloween and to hopefully help to cut costs, but a few months ago I started a new 9-5 job and have really grown to like a few of the girls in my office and would like for them to be able to come so I have been considering pushing it to a Sunday. Now here comes the problem. One of the girls in my office I do not want to invite. If I do change the date to a Sunday is it rude of me to invite the other girls and not her?
